Antifungal agents are medications used to treat infections caused by fungi. These infections can affect various parts of the body, including the skin, nails, and lungs. Common antifungal agents include fluconazole, itraconazole, and amphotericin B. They work by targeting the cell membranes of fungi, disrupting their growth and reproduction. There are two main types of antifungal agents: topical and systemic. Topical antifungals, like clotrimazole, are applied directly to the skin, while systemic antifungals are taken orally or injected to treat more severe infections. Proper use of these medications is essential to effectively combat fungal infections and prevent resistance.
